ZTE, China Mobile and Qualcomm have announced they have demonstrated gigabit data speeds on a TD-LTE commercial network in Quanzhou, Fujian, using “pre-5G” technologies including multi-carrier aggregation, 4×4 MIMO and 256QAM.
In the same network environment, China Mobile and ZTE further verified the gigabit solution by utilizing Qualcomm’s commercial Snapdragon 835 platform, in which the peak rate reached 700 Mbps with a 10-stream data transmission on a single phone.
Prior to this, Quanzhou Mobile and ZTE jointly launched commercial deployment of 3D-MIMO in big video environments. With 16 commercial terminals connected, the single-carrier downlink peak cell rate was close to 730 Mbps, while the single-carrier 16-stream downlink peak rate of 3D-MIMO reached 700 Mbps, equaling a three-carrier rate up to 2.1 Gbps.
ZTE said the field test indicates a step forward in single-user rate enhancement. By using 4×4 MIMO, multi-carrier aggregation, and 256 QAM technologies, as well as commercial chips on a commercial network, the solution improves efficiency of the network spectrum without increasing bandwidth, and provides a user data rate of 1 Gbps or above.
